Predictive text

Predictive text is a technology that facilitates input of text by predicting words based on keystrokes. "[A]ll predictive text systems have initial linguistic settings that offer predictions that are re-prioritized to adapt to each user." (Wikipedia, accessed 2015-10-22)

Early versions were designed for the cellphone keypad, as an input method more efficient than "multi-tapping" keys to get desired letters where each key represents more than one letter. Words are suggested based on keystrokes, and suggestions are modified with successive keystrokes. It is a feature used for SMS on mobile phones.

Predictive text systems include T9, iTap, and LetterWise/WordWise. In the mid-2000s, predictive text was developed for some African languages, notably of South Africa, by companies such as Nokia.

Predictive text also describes systems used on touchscreen smartphones? to facilitate typing.
